Solvent effect on reaction rate
WebWe have investigated the spontaneous degradation of aspartate and asparagine residues via succinimide intermediates in model peptides in organic co-solvents. We find that the rate of deamidation at asparagine residues is markedly reduced in solvents of low dielectric strength. Theoretical considerations suggest that this decrease in rate is due to the … WebT1 - Rate of Reaction of Electron Transfer over a Long Range and Mediated by a Solvent. AU - Chen, Jin‐Ming ‐M.
